Question

Blocks I and ii , each with a mass of 1.0kg are hung from the ceiling of an elevator by ropes 1 and 2. What is the force exerted by rope one on the block one when the elevator is moving upwards at a constant speed of 2m/s?

Answer 1

When the elevator is moving upwards at a constant speed of 2 m/s, the force exerted by rope one on the block one is

$$T=m_1g.$$

If the motion was accelerated, the tension would not be equal to the force of gravity acting on the block one.
